Configuration Guidelines
•
If the interface is configured as a tunnel port, LLDP is automatically disabled.
• If you first configure a network-policy profile on an interface, you cannot apply the switchport
voice vlan command on the interface. If the switchport voice vlan vlan-id is already configured on
an interface, you can apply a network-policy profile on the interface. This way the interface has the
voice or voice-signaling VLAN network-policy profile applied on the interface.
•
You cannot configure static secure MAC addresses on an interface that has a network-policy profile.
• You cannot configure a network-policy profile on a private-VLAN port.
•
For wired location to function, you must first enter the ip device tracking global configuration
command.
